I hope this is an API topic I'm trying to come up with a way to basically use exploding dice in a way that transfers the bonus to a different roll. For example, I want an attack with accuracy 1d20-4 and damage of 1d8+5+@{selected|attack} to function such that if you roll a 20 on the d20, you add the 1d8+5 again to the second roll (1d8+5+@{selected|attack}+1d8+5) Also I have no idea how to use API, so I'm just hoping this exists already.
